Be it known that 1Dznnennr D. Hit-Lon- MAmaa citizeniotthefUnited States, residn ing at Aberdeen, in` the` county of Brown and State ofSouth Dakota, have invented lnew and useful Hose-Couplinfr Locks, of

which the following is aspecihcation, reference being had tothe accompanying drawings Vand to the letters and iigures of reference h marked thereon.

This invention relates .to the typt#` rOg' hose#k coupling that comprises tvvofoounterpart .coupler heads of the Classthatis used o-n the ends `of air-brake, air-signal and steamheating pipes on railway cars, `for connectmg `the PIPQS of the different CMS together,

each coupler head being connected "to the pipe by lmeans `of "a section of hose, the coupler heads being connected together in a well known manner; the invention having reference more particularlyto devices for locking the vent leakage at thecoupling joint during operation of the railway trains.

` An Vobject of the'invention is to provide a simple and convenient hose-coupling lock that may becheaply constructed and which shall be eiiicient to prevent the sections of hose from buckling up vand causing leakage when the'slack in the train runs in and out during movement of the cars; another obiectlbeng to provide an eiicent `look for hosecojuplings that will Permit the coupler heads to pull' apart withoutdamage to the parte in. das@ the Celis become elcoupled, which lockingdevice shall .be of such construction `astobe 1durable and economical use'andV not be a hindrance in the'operations of connecting ord-isconnecting the coupler hea'dsbut rather facilitate such operations.

With the abovementioned and otherobjects inview the invention consists in ipair of counterpart coupler heads proyided'each with an improved lockingdevicewand also a notch or recess to receive the device" of the companion' conpler head; the invention consisting also further in the novel parts andA combinations `and arrangements of parts as hereinafter particularly described and further defined in the accompanying claim.

Referring to the drawings,-Figure l is a side view of a complete hosecoupling, the sections of hosebeing fragmentary; Fig. 2 is a perspective view of the improved locking device; Fig. 3 is a'. front vlew of one of coupler heads together to pre-- "speciacation'f Letters raient. i i Patented Decre, 19M;

Similar reference characters on the ditferent figures of the drawings indicate corresponding :elements or features ci construction herein referred to.

In the drawings the numerals l and 4l indicate two sections of air-brake hose to each of which in common practice a coupler head of well known construction is secured, the coupler heads being identically alike `but are arranged in relatively` reversed order and respectively comprise bodyportionsV and 2 havingshank portions 3` and 3 `that are directly connected to'the hose sections, the headsfhavilg also. elbow portions 4 Aand 4 provided with'joint portions 5 and 5 in which are they orifices of the ducts `that extend `through the head," the jointportions .havingl gaskets `(i and 6" therein that are brought together `when the `two heads are coupled 'together'. The ends of the heads have,erespectively, suitable projections 7 `and that 4extendirom the elbows adjacent to the joint portions, the backs ot the pro jections having ribs. S and 8 thereon.` The body portions have arms 9 and 9 on the fronts thereof that have projections 10 and 10 behind whichtofreceiye the ribs `Sor 8 of the companion head and have also n l andfl'l on the inner side `thereof to be engaged by the`rib 8` or"87 to lsecure the heads together. I he projections 1.0and X10 have ears `l2 and 12 on their "normal lower nds respectively `and the body portions have earsl and L13 respect j portions, a stop pinlfi heilig-secured tothe earsgl and 13, a stopfpnrfl beingsecuijed to the (ears .12"@61 '13"tobee1isased by th projections `7 or 7 when the heads are properly Couplefltosether. The `body Portions 2 hand 2 are curved and in order to connect the heads together their ends are turned upward to permit the gaskets to be brought together, after which the heads are turned downwardly with the gaskets connected together until the projections 7 and 7 are brought behind the projections l0 and 10 respectively and stopped againstvthe stop pins, in which arrangement the heads are Y in Acontact with the projection 10.

connected together but may be forcibly pulled apart when the train breaks, as is well known. Y

For the purposes of the invention the front of the arm 9 is provided with hinge ears 15 and 16, the arm 9 being provided with similar ears 15 and 16 that extend along the front of the projections 10 and 10 respectively. A pivot 17 is connected to one pair of ears, a similar pivot 17 being connected to the other pair of ears. Each couple'r' head is provided with a lock barto engage the companion head, the lock bar being in theform of a lever that is connected between its ends to the pivot 17 between the ears 15 and 16 so as t0 constitute a locking portion 1S and a lever arm 19 that has an angular portion 2O so that the lever portion extends along the exterior of the hose section 1, the locking portion 18 normally ex-` tending 'against the projection 10 and a suitable distance beyond the projection.` The companion lock bar is connected to the pivot 17 and has a lock portion 18 and also a lever 19', the lock portion being normally l The lock bars are yieldingly held in normal position by ineans ofsp'rings 21 and 21 respectively which preferably are coiled,one spring being seated in a socket'QQ formed in the arm 9 and another socket'QB formed in the lever 19 adjacent to the pivot 17', the spring 21 being seated in a socket 22' formed in the arm 9 and also in a socket 23 formed in the lever 19. The back of the projections 7 and 7 have ribs 24 and 24 thereon respectively, the ribs preferably being circular and extending about the curved exterior of the elbow portions 4 anda respectively;` said ribsl having recesses or notches 25 and 25 therein respectively, the notch 25" being adapted to receive the lock portions 18, the recess 25 being adapted to receive the lock portion 18', so as to prevent the headsfrorn being accidentally turned upward Vas is done when uncoupling the heads one from another. l In practical use the workman when grasping the hose sections in the customary inannerr to coupletlie heads together,` conveniently presses the levers 19 and 19 against the hose sections which retracts the'lock portions 18 and 18 and permits'the heads to be coupled in the customary manner, the

`Copies ofthis patent may be obtained for levers being released when the heads are connected and the lock portions being permitted to, enter therecesses or notches de-A signed to receive them. Y ment of the train of cars, as the slack in the draw bar connections runs in or out, the tendency is to swing the house couplings and jerk them upwardly and thus cause leakage at the joint, as is well known, the couplings in normal position being suspended approximately as illustratedin Fig.u 1 inwhich position the couplings are maintained by means of the 'locks as hereinb'efore -dej scribed. In case thejcar couplers become dis- During the moveconnected, the hose coupler being connected together, the locking bars permit the cou`V pling heads to'be forcibly pulled apart withoutV causing damage since the lockingpor-l tions slip away Alongitudinally from the recesses or slots of the companionheads.l
